Soft tissue sarcomas of the extremities and trunk in the adult. Report of 124 cases

Abstract

Between 1970 and 1988 surgery was performed on 124 patients with soft tissue sarcomas of the extremities and trunk in the University Clinics of Hamburg. Liposarcoma, malignant fibrous histiocytoma, fibrosarcoma and malignant schwannoma were the most common histological types. High-grade sarcomas (G3) predominated, with 41%, while 26% were graded G2 and 33% G1. Resection with wide margins all round was achieved in only 54% of the patients. The quality of the operation proved to be only therapy-related prognostic factor. In addition, tumour grade, size, regional lymph node and distant metastasis and histological type proved to be relevant to the prognosis. With multivariate analysis, distant metastasis, grade, resectability and histological type retained prognostic significance. The efficacy of adjuvant chemo- and radiotherapy was related to the quality of the preceding tumour resection. In case of gross tumour the rate of either partial or complete response was 28% for chemotherapy and 22% for radiotherapy. The mean survival time was 102 months; the 5- and 10-year survival rates were 48% and 37%, respectively.
